As the name tells, a starter motor is an electrical motor which is applied to start an internal combustion engine in large machine such as car, truck, crane. Typically starter motor is a very low-geared device and is able to crank over the much larger engine due to its extreme gear reduction. The starter motor belongs to a starting system composed of the starter, a starter solenoid and the battery. When the ignition switch is turned, it sends an electrical charge to the starter solenoid. This, in turn, sends the charge to the starter motor that cranks the engine until it starts. Once the engine fires successfully, the starter motor clicks off and disengages the starter ring.
